JOSEPH F. CRAWFORD, OF ELMIRA, NEW YORK, ASSIGNOR TO THE GRANV- FORD MOTOR COMPANY, OF SAME PLACE.

DEVICE FOR CONVERTING MOTION.

SPECIFICATION forming part of Letters Patent No. 303,989,

dated August 26, 1884.

Application filed December '7, 1883. (No model.)

I 0 all whom it may concern.-

Be it known that I, J osnrrr F. CRAWFORD, of the city of Elmira, county of Ghemung, and State of New York, have invented a new and useful device for transferring rectilinear and reciprocating motion into rotary motion without the use of a crank, of which the following is a specification.

I attain this object by the mechanism illustrated in the accompanying drawings, in which is a vertical section of the entire Figure 1 machine. Fig. 2- is ascctional vlew of apawlholder.

Similar letters refer to similar parts described in this specification.

A represents a lever.

B is the fulcrum.

O, I), E, and F is the lever-head, to which A. is firmly attached.

G is the point to which the power is applied.

K represents a gear between two pawl-holders.

L represents one of the pawl-holders, and L its fellow upon the opposite side of the gear.

K represents the attachment of connectingrods to L and L.

N N represent the connecting-rods.

O 0 represent the pawls in the inside of L and L, and M the shifter. The lever A, with its head 0, D, E, and F, is mounted upon a shaft at B, which becomes a fulcrum, the resistance being applied at the points E and F or at O and D, or at any point of a line of a circle concentric with the fulcrum B. The resistance must be applied at an equal distance from the fulcrum B. By the application of the power at the point G, E and Fwill be car- :ried in opposite directions from a line running perpendicular through F, B, and E.

L and L are pawl-holders placed upon the same shaft, facing each other, and having flanges so adjusted as to extend over and completely inc-use the gear that works between them.

K is the points of connection between the main lever and L and L.

N N are the pitman-rods, the end of one bein attached at F and the other at E, while the other ends are attached to L and L at the points K, when the lever A, is vibrated, E

and F moving in opposite directions by means of N N. L and L are also carried in opposite directions at the same time by the action of the lever A.

O and O are the pawls in the inside of L and L, and K the gear into which they mesh.

It will be seen when,by the action of the lever A, E is carried forward, the pawl O,ineshing into K in the inside of L will carry K forward with it. The same result will be seen as between F and K and Land K. The pawls O and O are so adjusted that by throwing one in gear and the other out of gear in L and L a forward or backward movement is given to the pinion K. The slide M passes through 0 and O, and being made in the form of a double inclined plane, with the small ends together, when M is pushed to the left 0, will be held up and 0 drop down, and when can ried to the right 0' will be carried up and 0 drop down into its workingposition. By this arrangement the application of power at G will transmit the motion from the piston of a cylinder from the hand or any other rectilinear and reciprocating motion without the use of a crank.

The lever may be constructed in any proportion to give an increase of power.

Having described my invention, what I desire to secure by Letters Patent is- 1. The combination of coggear K between two pawl holders, with their pawls meshing into it, as shown, and for the purposes set forth.

2. Two pitmen attached at opposite sides of the fulcrum of a lever, and connected with the pawl-holders upon the same side of the shaft upon which they are mounted, for the purpose of transferring rectilinear and reciprocating motion into rotary motion, as described.

3. Two pawl-holders, arranged as shown in L and L, and forming an incasement of the gear K, in a device for transferring rectilinear and reciprocating motion into rotary motion, as described.

4. The slide M, in combination with the pawls O and O, as and for the purposes set forth.
